If you have a lot of guests, then unless the names are organized alphabetically, it will take a long time for each person to find their name since they’ll have to look through every single table to find their name. There are lots of pretty ways to display escort cards by table number, but it’s definitely easier for guests if you organize the escort cards alphabetically.

I personally would like something I could take with me. I can totally see myself looking at the board and thinking “okay I’m table 9” then wandering toward tables and meeting a friend and chatting and totally forgetting my table number so I have to go look again. But maybe I’m overly spacey.
